All the sites I used to use to rip to mp3 don't work with the new YouTube Music (music.youtube.com) Suggestions?
https://2conv.com/ On music.youtube.com go to the track to be downloaded. Go to 3 dot menu and get the share link of the track. Copy and paste it there (link from above). Press convert button. If there is no share link at first place, go to "Start radio". Now go again to the three dot menu and get the share link from the new page. Tested it recently. Still works.
